If all goes to plan, Oceania Sirena will be leaving the Oceania fleet after her spring 2028 season.
Although a buyer has yet to be named, the ship's owner, Norwegian Cruise Line Holding, is understood to have agreed terms.
The 684-guest ship originally launched in 1999 as the R Four for Renaissance Cruises. Then, after 14years sailing as Tahitian Princess and Ocean Princess for Princess Cruises, she joined the Oceania fleet.
